BQ24650EVM-639 is a Evaluation Modules (EVM) used to demonstrate the capability of the BQ24650 Synchronous step-down Silent Switcher™ integrated circuit (IC). The BQ24650EVM-639 can be used as a reference design for power management in portable audio applications. Ratings of the EVM include an input voltage from 4.5V to 36V and a regulated output voltage from 0.6V to 5V.

The BQ24650EVM-639 provides a platform to evaluate the features of the BQ24650, a high-efficiency, digital power-management unit. It has an integrated low RDS(ON) synchronous MOSFET which allows it to achieve up to 95% efficiency. It also features low quiescent current, cycle-by-cycle current limit, thermal shutdown, adjustable soft-start, hiccup/CDM circuitry, and overvoltage protection. The EVM operates with an adjustable maximum switching frequency of up to 4MHz.

The BQ24650EVM-639 utilizes an onboard, ultra-low power microcontroller for use in controlling all functions of the BQ24650 IC. It also includes GUI interface software to allow for the adjustment of the power settings. The GUI software allows for the control of the power switch, enable pin, digital power control pin, output voltage, soft-start, maximum current limit, voltage-over-time limit, overvoltage protection, and power up/down sequencing.

The BQ24650EVM-639 can be used in many applications such as portable media players, e-book readers, portable DVD and Blu-ray players, point-of-sale terminals, and more. It can also be used to evaluate the performance of an IC in an actual application, allowing designers to develop a complete power management system.

The BQ24650EVM-639 is a great platform to evaluate the capabilities of the BQ24650 IC and its working principle. It has a wide variety of features and settings that can be adjusted to accommodate a wide range of applications. Additionally, the EVM includes an onboard microcontroller and GUI software for easy evaluation and demonstration.
